MALIBU — Adrianna Nunez started running track this year to help her in soccer. She's getting a little more out of the sport than just exercise.

The freshman from Santa Paula High had wins in all four of her events — three individual races and a relay — to highlight individual performances at Thursday's Frontier League track and field championships at Malibu High.

"I've been doing club soccer," said Nunez, "and I just started track this year because I wanted to stay in shape, and I'm doing well."

No kidding.

Nunez posted her wins in the 400-meter run (in 1 minute, 5.73 seconds), the 800 (2:38.80) and the 1,600 (5:44.64), and joined with Katie Gialketsis, Sarah Black and Victoria Olivia to win the 1,600 relay in 4:36.29.

Malibu standout Emani Truluck also had three individual victories, in both hurdle events and the triple jump, while five athletes had two individual victories. League champions qualify automatically for the CIF-Southern Section Division IV prelims; second- and third-place finishers also advanced if they met qualifying marks.

Santa Paula won both the boys' and girls league titles for the second straight year. The girls had clinched the title entering Thursday's meet, while the boys used their win Thursday to edge Santa Clara, which was seeking its first boys' track title since 1963.

Nunez said the 4x400 relay is her favorite event — "I like the racing," she said — and that she particularly enjoys the 400 among the others. "It's fun," she said. "It's a full sprint, and I like sprinting."

Truluck, who came into the week with some of the area's best marks in all three of her events, cruised to wins in both the 100 hurdles (14.65) and 300 hurdles (47.19) and won the triple jump with a mark of 31 feet, 7 inches, although she said she "didn't do too great," in her field event.

"I ended up doing a five-step approach," Truluck said. "I figured I could still take the win and preserve my body. And the 300 hurdles, I was all over the place, but I qualified. I know I have that room to try new things, because I still know I can win."

Truluck, who had qualifing marks nearly six seconds better than anyone else in the 100 hurdles field and almost nine seconds better in the 300, has tried to get through the season prepared for the different level of challenge she'll encounter in CIF competition.

"That's why I go to the big meets, like Arcadia and Mount SAC," she said, "so I can see all the good girls and raise my competition level. And I practice hard every day. "In the boys' meet, double winners included Steven Graham of Santa Paula in the 1,600 and 3,200; Cierre Wood of Santa Clara in the 100 and Joey Bui of Villanova in the long jump and triple jump. Wood later scratched from the 200 after tweaking a hamstring in his lunge for the finish in the 100.

Graham, another first-year runner for the Cardinals, posted times of 4:53.20 in the 1,600 and 10:54.48 in the 3,200.

"I'm looking forward to CIF," said Graham, "because I want to run (the 1,600) against somebody that's real fast. I'm looking forward to seeing how I can do against someone running close to a four-minute mile. My goal for senior year is a 4:11.

"And the 3,200, I look forward to never running that race again."

Winning twice in the girls' competition were Santa Clara's Diedra Bridgett in the shot put and discus, and Bishop Diego's Melissa Georgi in the 100 and 200.

Bridgett posted marks of 27-1112 inches in the shot and 79-7 in the discus on something of a frustrating day.

"It wasn't a good day for me," Bridgett said. "I was mainly concerned with the discus. I was trying to break the record, which is 99 feet. I was trying to break 100. It didn't happen today; hopefully it will happen at prelims.

"It wasn't a great throwing day. I could have PR'd today with a 33 in the shot, but I kept falling out of the ring. Same thing with discus. I could have PR'd, but they went out of the sector at 100 feet. It was just my balance and the way I was kind of feeling today."

Now the question for Bridgett is if she'll be able to compete in prelims, since they conflict with an exam she needs to take for admittance to San Francisco State.

"I'm going to see if the field will be open all day," Bridgett said. "I should get there about 2 p.m. after taking the test at (Cal State Channel Islands). Once I do that, I'm ready to go."
